Matching questions 1. velocity 2. speed 3. gravity 4. deceleration 5. newton a acceleration in the opposite direction as the velocity of the object; results in speed decreasing b the rate at which an object changes position when traveling in a certain direction, expressed as a rate: distance divided by time + direction c force of attraction between all masses in the universe d the unit of force in the metric system; it is a unit derived from mass and acceleration (speed over time in a direction) e the rate at which an object changes position; distance divided by time

1. Velocity match with B

2. Speed watch with E

3. Gravity match with C

4. Deceleration match with A

5. Newton match with D

Explanation:

1.)

  Velocity is defined as the time rate of change of displacement. It is a vector quantity. So it has certain direction as mention in option B. So B is the correct matching.

                         v  = Δd/Δt

2.)

   Speed is defined as the time rate of change of distance. It is a scalar quantity. It is same as velocity but only difference is that velocity has magnitude as well as direction but speed has only magnitude. As in option E, direction not mentioned. So E is the correct matching.

3.)

  Gravity is the force of attraction between any two objects, two masses. It is not only the force between body and the Earth but it is the force that exist between any two bodies in the universe. C is the correct matching.

4.)

  Deceleration is actually the acceleration but in the opposite direction. It is also called negative acceleration. When the velocity of the object increasing it is acceleration and when velocity decreasing it is called deceleration. It is always opposite direction to velocity. So A is the correct matching.

5.)

   Newton is the name of the scientist. Also it is the unit of force in metric system. Here newton means unit of force because n of newton in small letter. From Newton's second law of motion

                              F = ma

                                 = (kg)(m/s²)

                                 = N

Thus,

                                N = kgms⁻²

Option D is correct matching.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
